I don't get the obsession with yall hating on halal meat. It's actually 10x cleaner because they slaughter it the right way and all the blood goes out the neck. Halal meat is actually better for you. It's Cleaner and they treat the animal with kindness unlike how factories do it
Slaughter the Animal with a sharp knife or tool. 
Directly pierce the throat, windpipe and blood vessels of the animal
Drain the blood
Most humane way of slaughter to an animal is the halal way and also an extra point is that it should not be done in front of other animals so they don't get scared. They shouldn't even know about whats about to happen.
